I'm trying to work on an old Visual Studio 2010 project from another computer, but I forgot the password for the pfx file used to sign the assembly. Is it possible to crack the password or is there a way to build the project without knowing the password?
There are no way that can get the password from a pfx file unless you remember it. I suggest you restore previous Windows 7 from Windows. old folder, then decrypt these files to get access.
The PFX file is always password protected because it contains a private key.
A lost certificate password cannot be recovered. However if the certifictate is still in the Certificate Store it can be re-exported with a new Certificate Password.
If you remember certain characteristics about your password (i.e. starts with 'pass', does not contain tilde, ampersand, digits 6 - 9, etc...) you could use this utility (boredwookie.net) I wrote to help you recover the password. It is released under an Open Source (MIT) License so you can see how it works.
